Convert text to image in ASP.NET

In this blog we will learn how to convert text to an Image.

I have an ASP.NET page that has a TextBox control. When user enters any text to the TextBox and clicks the button, then the text is converted to an image.


Note: - Here we need two namespaces.

using System.Drawing;

using System.Drawing.Imaging;


<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %>


<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">


<html xmlns="">

<head runat="server">

    <title>Untitled Page</title>



    <form id="form1" runat="server">


     <asp:TextBox ID="TextBox1" runat="server" Width="200px"></asp:TextBox>

        <br /><br />


        <asp:Button ID="btnconvert" runat="server" Text="Convert to image"

            onclick="btnconvert_Click" />

        Graphics gph1 = Graphics.FromImage(bit1);

        string text;


        text = TextBox1.Text;

        gph1.DrawString(text, new Font("Arial", 12, FontStyle.Bold),

        new SolidBrush(Color.Red), new PointF(0.4F, 2.4F));

        Response.ContentType = "image/Jpeg";

        bit1.Save(Response.OutputStream, ImageFormat.Jpeg);
